Expanded Clay Aggregate in Engineering: Crushing Behaviour and Design Implications - Hardcover

Über die Autorin bzw. den Autor

Adel Kmema is a Senior Lecturer in Civil Engineering at the Higher Institute of Technological Studies of Rades, Tunisia. He is a member of the Civil Engineering Laboratory (LGC) at the National School of Engineers of Tunis. His research investigates the multi-scale mechanical behaviour of granular materials, with a specific focus on particle crushing in lightweight aggregates. He has developed novel experimental methodologies, including color-coded grain tracking and strain-threshold testing, to directly observe crushing evolution from individual grain fracture through assembly-scale response. His work on expanded clay aggregate has established fundamental force-size relationships, quantified energy dissipation through crushing, and developed modified Weibull frameworks incorporating coordination number effects. His research bridges the gap between micromechanical understanding and practical geotechnical design.

Elhem Ben Ammar is a Senior Lecturer in Civil Engineering at the Higher Institute of Technological Studies of Rades (ISET Rades), Tunisia, and a member of the Civil Engineering Laboratory (LGC) at the National School of Engineers of Tunis (ENIT), Tunisia. Her research and publications focus on granular materials and geographic information systems (GIS). She is actively involved in teaching activities in civil engineering. She is currently working within a collaborative framework on the study of the effect of fragmentation on the behaviour of granular materials.
